Description

Adhesive braided net and binding net Technical Field

[0001] The present invention relates to the technical field of netting, and more particularly to an adhesive netting and a binding netting. Background Art

[0002] In agricultural production, it is common to use disposable elastic nets to bundle straw and forage grass. This elastic net is usually called a baling net, or a grass wrapping net. Baling nets must meet certain strength requirements and, on top of that, must be as lightweight as possible, as production costs are directly related to weight.

[0003] Currently, most bale nets are woven using warp knitting machines, resulting in high production efficiency. The structural characteristics of bale nets are large mesh sizes, and their functional requirements are a certain degree of load-bearing strength. The bale net shown in Figure 1 consists of several warp chains running parallel to the warp direction. Each warp chain is composed of a series of links formed by looping warp yarns. Weft inserts are placed along the weft direction between adjacent warp chains, forming a mesh structure. Because of its warp knitting structure, loops are formed between the coil links in each warp chain, and between the weft inserts and the coil links. This results in a knot-free mesh structure, preventing knots and loss of strength.

[0004] Although this structure avoids knotting, due to the continuous winding and looping of the warp threads, there will be a 30%-40% strength loss when subjected to stress. To avoid this, the existing technology has improved this structure. As shown in Figure 2, a lining warp is added to the warp chain. The lining warp is distributed in a straight line to increase the warp strength. This technology is described in detail in the patent: A lining warp chain structure for woven nets and a bale net using the same (application number: 202010029976.7).

[0005] This technology is also recorded in U.S. Patent Publication No. US20200385902A1.

[0006] Although the strength is increased by adding lining warp, due to the existence of both warp and lining warp, the denier of warp and lining warp needs to be strictly controlled under the condition of certain quality of bale net. Otherwise, even if the strength is improved, the production cost will increase due to the increase in overall weight, and the possibility of actual application is low.

[0007] Therefore, for the current binding nets, how to improve their strength without increasing their weight is a difficult technical innovation problem faced by the industry.

[0008] Summary of the Invention

[0009] 1. Technical problem to be solved by the invention

[0010] The purpose of the present invention is to overcome the problem of knot loss in the existing mesh due to the looping of the warp yarn, and to provide a cohesive mesh and binding mesh. In this solution, the intersection points of the warp yarn and the weft yarn are connected by bonding, which eliminates the knot loss of the warp yarn during weaving and improves the strength of the mesh.

[0011] 2. Technical solution

[0012] In order to achieve the above object, the technical solution provided by the present invention is:

[0013] The present invention provides an adhesive braided mesh, comprising warp yarns and weft yarns, wherein the warp yarns are arranged parallel to the longitudinal direction, the weft yarns are distributed in a zigzag pattern between two adjacent warp yarns, and the intersections of the warp yarns and the weft yarns are connected by bonding; and the elongation of the warp yarns in the braided mesh is 30%-80%.

[0014] Furthermore, the warp yarns and the weft yarns are yarns made of polyethylene or polypropylene or a combination thereof;

[0015] Or: the warp yarn and the weft yarn are both polyethylene yarns, and the intersection points of the warp yarn and the weft yarn are connected by thermal bonding.

[0016] Or: one of the warp yarns or weft yarns is a monofilament yarn or a membrane yarn made of polyethylene or polypropylene or a mixture of the two.

[0017] Furthermore, the warp yarn is 600-1200 denier yarn.

[0018] Furthermore, the weft yarn forms fulcrum folds at both ends in the weft direction, and the fulcrum fold ends of the weft yarn are connected to the warp yarn;

[0019] Or: the weft yarn forms a fulcrum fold at both ends in the weft direction, the fulcrum fold forms two connection points at the intersection with the warp yarn, and forms a loop with a gap between the fulcrum fold and the warp yarn;

[0020] Or: the weft yarn forms a fulcrum fold at both ends in the weft direction, and the fulcrum fold forms two connection points at the intersection with the warp yarn, and forms a ring with a gap between the warp yarn, and the distance between the two connection points is 2-8mm.

[0021] Furthermore, the warp yarns are located on the same side of the support angle side line, or pass between two side lines forming the support angle.

[0022] Furthermore, the distance between two adjacent warp yarns is 1-8 cm.

[0023] Furthermore, the warp yarn includes 1-4 sub-yarns arranged in the warp direction, and when there are more than 2 sub-yarns, the multiple sub-yarns are arranged in parallel in the weft direction.

[0024] The adhesive braided net of the present invention comprises warp yarns and weft yarns. The warp yarns are arranged in parallel along the longitudinal direction, and the weft yarns are distributed in a zigzag shape between two adjacent warp yarns. The intersections of the warp yarns and the weft yarns are connected by thermal bonding.

[0025] Furthermore, the warp yarn or weft yarn is a monofilament yarn or a membrane yarn made of polyethylene or polypropylene or a mixed material of polyethylene and polypropylene.

[0026] Furthermore, the weft yarn includes 1-4 sub-yarns arranged in the warp direction, and when there are more than 2 sub-yarns, the multiple sub-yarns are arranged in parallel in the weft direction.

[0027] Furthermore, the stretching rate of the sub-line is 40%-75%.

[0028] The present invention provides an adhesive woven net, comprising warp yarns and weft yarns, wherein at least two of the weft yarns are arranged in parallel in the weft direction, and each weft yarn is serrated, with the fulcrum folding angles of the weft yarns at the weft end being located at the same weft height; each weft yarn has 2-8 warp yarns arranged in parallel in the warp direction, and the intersections of the warp yarns and the weft yarns are connected by thermal bonding.

[0029] Furthermore, the width D of the weft yarn is 2-20 cm.

[0030] Furthermore, the spacing P between the folded corners of two adjacent supporting points on the same side of the weft yarn is 2.0-7.5 cm.

[0031] Furthermore, each weft yarn is connected to at least three warp yarns.

[0032] Furthermore, the warp yarns are distributed at equal intervals.

[0033] Furthermore, the warp yarn or weft yarn is polyethylene monofilament yarn or polyethylene film yarn.

[0034] Furthermore, the weight of the mesh is 3.5 g / m 2 ~7.8g / m 2 .

[0035] Furthermore, the warp yarn stretching rate is 35%-70%.

[0036] Furthermore, the stretching rate of the weft yarn is 40%-75%, and the stretching rate of the weft yarn is not less than the stretching rate of the warp yarn.

[0037] The binding net of the present invention adopts the above-mentioned adhesive woven net structure, and the adhesive woven net is wound to form a columnar structure.

[0038] Furthermore, the binding net also includes a core tube, and the braided net is wound on the core tube.

[0039] Furthermore, the core tube is a paper core tube or a plastic core tube.

[0040] The key to this invention is the zigzag design of the weft yarn, which is bonded to the parallel warp yarns. While bonding is possible if the warp and weft yarns are arranged in a straight line, there are significant problems. First, because the weft yarns are arranged in a straight, parallel line, each weft yarn must be laid from the first warp yarn to the last warp yarn. This requires cutting the yarn after laying, then running a certain distance in the warp direction before laying the next weft yarn, making continuous production impossible. Second, if a single weft yarn is wound back and forth from left to right, the travel distance is long, resulting in low production efficiency.

[0041] The invention adopts a sawtooth structure, which can perform wire laying processing according to width requirements. Each weft yarn has a pay-off needle, which moves left and right within its swing range. The warp yarn and the weft yarn work online at the same time, which can carry out continuous production with high efficiency.

[0042] 3. Beneficial effects

[0043] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0044] (1) In the adhesive braided mesh of the present invention, the warp yarns are arranged parallel to the longitudinal direction, and the weft yarns are distributed in a zigzag pattern between two adjacent warp yarns. The intersections of the warp yarns and the weft yarns are connected by bonding. Since there are no knots in the warp yarns, the loss of the warp yarns during weaving is eliminated, and its strength can be improved. The elongation rate of the warp yarns in the braided mesh is 30%-80%. On the basis of having a certain degree of stretchability, a large tensile strength is maintained.

[0045] (2) In the adhesive mesh of the present invention, the weft yarns are distributed in a zigzag shape between two adjacent warp yarns, and the zigzag ends of the weft yarns form a fulcrum ring with a gap with the warp yarns. The fulcrum ring is used to cooperate with the fulcrum to shape the weft yarns during weaving, so that the weft yarns can form a zigzag structure with a smaller width, thereby controlling the width of the mesh and improving processing efficiency.

[0055] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0056] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose of the present invention. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0057] FIG1 is a schematic diagram showing a structure of an existing bale net, in which warp chains 1 are arranged in parallel and connected by weft inserts 2. This structure reduces strength because the warp threads in the warp chains are looped.

[0058] Figure 2 shows the improved bale net structure. As an improvement, a lining warp 003 is added to the warp chain 001. The lining warp 003 adopts a straight structure without knotting or winding, so there is no direct knot loss and it can provide the main pulling force in the warp direction.

[0059] The use of a straight-line structured warp insert can increase strength, but since it needs to be connected to the weft insert, it also needs to be used in conjunction with the looped warp to connect different warp threads and prevent the warp threads from moving after weaving.

[0060] Example 1

[0061] In conjunction with Figure 3, an adhesive mesh of this embodiment includes warp yarns 1 and weft yarns 2, wherein the warp yarns 1 are arranged parallel to the longitudinal direction, and the weft yarns 2 are distributed in a zigzag pattern between two adjacent warp yarns 1, and the intersection points of the warp yarns 1 and the weft yarns 2 are connected by bonding; and the elongation rate of the warp yarns 1 in the mesh is 30%-80%.

[0062] The distance between two parallel warp yarns 1 can be controlled within a certain range and can be adjusted according to the root packaging material. Generally, it can be set between 1-12 cm, for example, 3.0 cm, 6.2 cm, 8.4 cm, etc. The warp yarn 1 here does not refer to a single film yarn. In some embodiments, the warp yarn 1 can also be formed by twisting multiple silk threads.

[0063] The weft yarns 2 in this embodiment mainly play a connecting role, connecting the warp yarns 1 into a whole. In this embodiment, the weft yarns 2 are distributed between two adjacent warp yarns 1 in a zigzag shape.

[0064] It is worth noting that the serrated shape referred to in this embodiment and other embodiments refers to the overall shape formed by the weft yarns 2 alternating left and right along the warp direction, or the serrated shape formed by the weft yarns alternating left and right and the warp yarns, and does not require the serrated ends to be triangular or trapezoidal. As shown in Figure 3, the ends form a fulcrum angle, and the angle is a sharp angle; it can also be a structure as shown in Figure 5, where the fulcrum angle is a trapezoidal structure. In addition, what is shown in the accompanying drawings is the shape determined according to the state during processing. In actual products, since the warp yarns 1 and the weft yarns 2 are both flexible materials, in the absence of positioning, the fulcrum angle portion generally presents a free and loose special-shaped state, such as forming an arc, and it should also be considered that the whole is serrated.

[0065] In addition, since the weft yarn in this embodiment is zigzag-shaped and moves back and forth in a short distance, a fulcrum is required to shape the weft yarn to form this structure. During processing, the weft yarn changes direction at the fulcrum, thus forming a fulcrum angle.

[0066] In this embodiment, the intersection of the warp yarn 1 and the weft yarn 2 is connected by bonding. For example, during processing, hot melt glue is first placed at a fixed point on the warp yarn 1 or the weft yarn 2, and then bonded through a heating zone or hot pressing, or directly bonded without heating by other means.

[0067] Warp yarns 1 and weft yarns 2 can be made of polyethylene or polypropylene, or a mixture of polyethylene and polypropylene. Films are formed through a film-forming process and then cut into yarns. Because tensile strength and elasticity are inversely related under certain circumstances, the finished netting needs to withstand significant tensile forces during use. To ensure its strength, in this embodiment, the elongation of warp yarns 1 is limited to 30%-80%, for example, 32%-40%, 45%-55%, 56%-62%, or 65%-80%.

[0068] The stretch ratio referred to in this invention refers to the ratio of the length of the warp yarn stretched to its original length when it breaks. Since netting is generally used under low load conditions, a certain stretch ratio and strength are required. Ignoring the effect of heating on the yarn in order to achieve thermal bonding will result in insufficient strength. Therefore, the stretch ratio of the warp yarn 1 after bonding into the net is required to be between 30% and 80%. A more optimal range is 45% to 70%.

[0069] Example 2

[0070] Figure 4 shows a specific embodiment, in which the warp yarns 1 are arranged in parallel, the weft yarns 2 are distributed in a zigzag pattern between two adjacent warp yarns 1, and the ends of the weft yarns 2 form a support angle 3, the ends of which are connected to the warp yarns 1.

[0071] With this structure, the warp yarn 1 needs to pass between the two side lines of the fulcrum fold, so that the end of the fulcrum fold just touches the upper and lower sides of the warp yarn 1. This method can be bonded during weaving using a dispensing process, or the yarn can be woven first and then thermally bonded.

[0072] Thermal bonding can be achieved by directly heating the warp yarn 1 and the weft yarn 2 to locally melt and bond them, that is, by locally heating them at a specific point to bond them together, or by using hot melt adhesive.

[0073] Example 3

[0074] As another embodiment of Figure 4, the warp yarns 1 are arranged in parallel, and the weft yarns 2 are distributed in a zigzag pattern between two adjacent warp yarns 1. The ends of the weft yarns 2 form a support angle 3, and the two side lines of the support angle 3 of the weft yarn 2 are laid on the same side of the warp yarn 1. The top end of the support angle 3 forms a connection point with the warp yarn 1.

[0075] For specific bonding methods, refer to the solutions in other embodiments. To achieve the mesh structure of this embodiment, a fulcrum is set to hook the weft yarn 2 to shape it, and then the warp yarn 1 and weft yarn 2 are connected by bonding. This inevitably forms a fulcrum angle 3 at the end, protruding from the warp yarn 1. When there is only one connection point, the fulcrum angle 3 is bonded to the warp yarn 1, and no gap is formed between the fulcrum angle 3 and the warp yarn 1. This method allows the fulcrum to support a portion of the weft yarn, avoiding the formation of gaps, and also eliminates the gap between the fulcrum angle and the warp yarn during bonding.

[0076] Example 4

[0077] Figure 3 shows another embodiment. In Figure 3, the fulcrum angle 3 of the weft yarn 2 protrudes from the warp yarn 1 in the weft direction, forming two connection points at the intersection with the warp yarn 1. A certain gap is formed between the fulcrum angle 3 and the warp yarn. After bonding, a closed fulcrum loop is formed. This fulcrum loop can be formed by the weft yarn alone or by the warp and weft yarns together. When the fulcrum is thin, the gap within the closed loop can be very small, less than 1 mm.

[0078] The bonding process differs significantly from the weaving process, which involves direct looping and connecting the weft yarns via knots. However, in the bonding process of the present invention, the weft yarn 2 is difficult to shape due to the need to avoid knotting of the warp yarns. Therefore, the yarn can be laid first to shape the weft yarns before the weaving process.

[0079] To achieve the mesh structure of this embodiment, a fulcrum is set to hook the weft yarn 2 for shaping. Then, the warp yarn 1 and weft yarn 2 are connected by gluing. This inevitably forms a fulcrum angle 3 at the end, protruding from the warp yarn 1. To simplify the process, this embodiment places the fulcrum outside the warp yarn, allowing the weft yarn to bypass the fulcrum and change direction. Since the warp yarn also moves synchronously and travels a certain distance, two intersection points are formed between the warp yarn 1 and the weft yarn 2. After gluing, the warp and weft yarns between the two connection points form a closed loop, namely the fulcrum loop.

[0080] It should be noted that, when bonding, the two intersection points between the warp yarn 1 and the weft yarn 2 can be an integral bonding point or two independent bonding points.

[0081] As shown in Figure 3, the fulcrum fold 3 is close to the warp yarn 1. When point gluing is used, only one bonding point can be used to bond the two connection points. If the distance between the two connection points is large, they can be bonded separately.

[0082] Example 5

[0083] Figure 5 shows another embodiment. In this embodiment, two warp yarns 1 are laid on the same side of the edge line of the support angle 3. The serrated parts of the warp yarn 1 and the weft yarn 2 form two connection points, and the distance between the two connection points is large, and the spacing can be 2-8mm. At the 2-8mm position, a closed loop is formed between the weft yarn segment corresponding to the support angle 3 and the warp yarn 1.

[0084] When the pitch is large, using a single pivot to position warp yarn 1 creates a large lateral distance in the weft direction, resulting in a large amount of excess weft yarn 2. As shown in Figure 6, pivot Q is located at a large distance from the yarn, forming a triangle with a large excess. Using pivots A and B together creates a trapezoidal shape with an excess length that matches the pitch, thus avoiding material waste.

[0085] It should be noted that no matter whether a single fulcrum or two fulcrums are used, the state presented after the mesh is woven is that there will be part of the weft yarn 2 on the edge of the warp yarn 1. This part of the weft yarn 2 is the edge material left over when the fulcrum shapes the weft yarn during processing. After processing, it appears in a relatively loose state and is not required to have a triangular or trapezoidal structure. It can also be an arc-shaped protrusion or other structure.

[0086] Example 6

[0087] FIG7 shows another embodiment, in which the warp yarn 1 includes 1-4 sub-yarns arranged in the warp direction, and when there are more than 2 sub-yarns, the multiple sub-yarns are arranged side by side in the weft direction.

[0088] When there is only one sub-thread, the warp yarn 1 is the sub-thread. When there are two or more sub-threads spaced apart, they together constitute the warp yarn 1 in this embodiment. Preferably, the sub-threads can have a spacing of 1-3 mm.

[0089] Example 7

[0090] As a further limitation of the warp yarn, the warp yarn 1 is a yarn of 600-1200 denier, such as 700 denier, 800 denier, 1000 denier, preferably a high-density polyethylene film yarn.

[0091] The distance between two adjacent warp yarns 1 can be controlled to be 1-8 cm, for example, 4.0 cm, 5.2 cm, 6.6 cm.

[0092] In the above embodiments, the weft yarns 2 are arranged in an array in the same state. In other embodiments, two adjacent weft yarns 2 may also be symmetrically distributed.

[0093] Example 8

[0094] As an implementation method, the adhesive mesh in this embodiment includes warp yarns 1 and weft yarns 2. The warp yarns 1 are arranged parallel to the longitudinal direction, and the weft yarns 2 are distributed in a zigzag pattern between two adjacent warp yarns 1. The intersection of the warp yarns 1 and the weft yarns 2 is connected by thermal bonding.

[0095] Specifically, the warp yarn 1 and weft yarn 2 are made of polyethylene film yarn, connected by glue-free thermal bonding. Polyethylene film yarn exhibits melt viscosity at a certain temperature, allowing the warp yarn 1 and weft yarn 2 to be bonded together by applying a certain pressure. This process requires no additional adhesive, making it easier to process. The stretch rate of the warp yarn 1 is limited to 45%-68%. The stretch rate of the weft yarn 2 is 45%-90%, and can be further limited to 45%-75%.

[0096] Preferably, the stretching rate of the weft yarn 2 is not less than that of the warp yarn 1. The weft yarn 2 mainly plays a weft-wise connecting role and can have a relatively large stretching rate.

[0097] As another embodiment, the warp yarn 1 may be made of polyethylene film yarn, and the weft yarn 2 may be made of other materials with similar properties. For example, the warp yarn 1 may be made of polyethylene or polypropylene film yarn, and the weft yarn 2 may be made of polypropylene film yarn; or both the warp yarn and the weft yarn may be made of a monofilament yarn made of a mixture of polyethylene and polypropylene.

[0098] Example 9

[0099] As an embodiment, based on Example 8, the weft yarn 2 includes 2-4 warp-arranged sub-yarns, with the multiple sub-yarns arranged in parallel in the weft direction. The sub-yarns and the weft yarn 2 are made of polyethylene film yarn. The elongation of the sub-yarns is 35%-65%, which can be further limited to 45%-58%. The elongation of the weft yarn 2 is 40%-75%.

[0100] Example 10

[0101] As an implementation method, the basic contents of the above embodiments can be combined. This implementation limits the distance between the warp yarns and the weft yarns. The distance S between the warp yarns 1 is 1-10 cm, and can be further limited to 3-8 cm, such as 4.0 cm, 6.0 cm, and 8.2 cm.

[0102] The width D of the weft yarn 2 is 2-10 cm, such as 2.5 cm, 3.5 cm, 6.0 cm, or 8.0 cm. The spacing P between two adjacent fulcrum folds on the same side of the weft yarn 2 is 2-7.5 cm, such as 4 cm or 6 cm.

[0103] Example 11

[0104] In conjunction with Figure 8, an adhesive mesh of this embodiment includes warp yarns 1 and weft yarns 2, at least two weft yarns 2 are distributed side by side in the weft direction, and each weft yarn 2 is serrated, with the support angle located at the same weft height; the warp yarns 1 are arranged parallel along the warp direction, and the intersection of the warp yarns 1 and the weft yarns 2 is connected by thermal bonding.

[0105] Each weft yarn is provided with 2-8 warp yarns. When there are two warp yarns 1, warp yarns 1 are placed at both ends of the zigzag pattern of weft yarn 2. When there are 3-8 warp yarns, the warp yarns can be evenly spaced. This structure allows the pay-off needles for each weft yarn to move within a certain range to form a zigzag pattern, thus enabling continuous production. In this embodiment, the width D of weft yarn 2 can be larger, ranging from 2 to 20 cm.

[0106] Since the warp yarn 1 and the weft yarn 2 are both flexible materials, when not positioned, the fulcrum angle parts generally present a free and loose irregular state. When tensioned, they can form an arc or a shorter line segment parallel to the warp yarn. It should also be considered that the whole is serrated.

[0107] As a specific embodiment, each weft yarn 2 is connected to three warp yarns 1. The warp yarns 1 are evenly spaced. The warp yarns 1 or the weft yarns 2 are polyethylene monofilament yarns or polyethylene film yarns.

[0108] The stretching rate of warp yarn 1 is 48%-65%. The stretching rate of weft yarn 2 is 50%-70%. The weight of the woven net is 3.5g / m 2 ~7.8g / m 2 . If the strength requirements are met, relatively lighter materials can be selected.

[0109] Example 12

[0110] This embodiment provides a binding net, which adopts the above embodiment of the adhesive braided net, or a combination thereof, and is formed into a columnar structure by winding the adhesive braided net. When in use, the width of the binding net can be braided and bonded as needed.

[0111] In some embodiments, the binding net further comprises a core tube, and the woven net is wound around the core tube to form a roll, which is the binding net. The core tube is a paper core tube or a plastic core tube.

[0112] The binding net can be used to bind straw, rice straw, and waste materials for packaging. The woven net can also be used for secondary processing to form products such as lifting belts. There is no specific restriction on the use environment.

[0113] The above description of the present invention and its embodiments is illustrative and non-limiting. For example, in some embodiments, the width of the weft yarn is described, but other widths may be used in other embodiments where not specifically described. In some embodiments, the warp yarn material is described as high-density polyethylene, but this feature may also be combined with features in other embodiments.

[0114] In addition, the polyethylene material or polypropylene material or their combination referred to in the embodiments may be added with a small amount of additives to improve the material properties when used, such as adding some materials to improve their meltability for easier bonding, and they should still be considered to be polyethylene materials or polypropylene materials or a combination of the two.

[0115] The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the drawings and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
